Westhope Lagoon Wastewater Treatment Plant, Westhope, North Dakota

Westhope Lagoon is a municipal wastewater treatment facility located in Westhope, Bottineau County, North Dakota. The plant serves a small population of 429 residents, typical of rural communities in the northern Great Plains region of the United States. The facility provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater plants. With a designed capacity of 189.27 cubic meters per day, the plant operates at full capacity based on reported discharge volumes. As a lagoon system, it likely uses natural biological processes in aerated or facultative ponds to treat wastewater before discharge. The treated effluent is discharged into local waterways that drain into the Souris River basin, which flows north into Canada and eventually into Hudson Bay. The plant plays a critical role in protecting local groundwater and surface water quality in this agriculturally intensive region, preventing nutrient and pathogen pollution in the sensitive prairie ecosystem.

The plant discharges into the Souris River watershed, which flows northward through North Dakota into Manitoba, Canada, and ultimately into Hudson Bay via the Nelson River system. This region features prairie pothole wetlands and seasonal streams that support migratory waterfowl and diverse aquatic life. Proper wastewater treatment is essential to prevent eutrophication and maintain water quality in these ecologically sensitive habitats.
